The burden of diabetes is rising rapidly worldwide posing an enormous socioeconomic and health challenge. The correlation between environmental changes and diabetes exists, however, the researchers hypothesize that temperatures increase the brown fat which lead to insulin resistance and diabetes. Numerous studies have documented a relationship between changes in seasons and glycemic control in patients with both type 1 and type 2 diabetes. Studies typically report that the highest HbA1c levels occur during the colder months and the lowest levels during the warmer seasons. Furthermore, studies indicate that diabetes increases the susceptibility of patients to the cardiovascular events that can be precipitated by air pollution. Several cohort studies showed greater T2DM risk to be associated with exposure to higher levels of NO and PM2.5. However, A better understanding of the environment–diabetes relationship can inform the formulation of policies that promote health and create opportunities for individuals to translate intentions into sustained behavioural change that are essential to curb the rising burden of diabetes.
